To all whom it may concern:

Be it known that I, EARLE E. 'CHAPMAN, a

citizen of the United States, residing at Los 1 Shackles for Automobile lVheels, of which the following is a specification.

My invention relates-to shackles which are adapted to be secured about the wheel of an automobile for the purpose of preventing theft or unauthorized use thereof. Such shackles are ordinarily secured about one of the front wheels being locked therearound so that the shackle is difiicult to remove and so that they will produce an unmistakable sound and make a plain trail in case the automobile is operated with the shackle in place thereon. 7

An object of the invention is to provide a shackle for this purpose which will make an unmistakable sound, preventing the automobile from running at a high speed, and which will a so leave a distinctive mark on the surface of the street n case the automobile is driven with the shackle in the place on the wheel thereof. For this purpose I provide a bumping member which is secured on the tread of a tire and provided with a sharp projection so placed as to dig into the street it the automobile is moved withthe shackle in place.

A further object of my invention is to provide shackle which will be of very low cost which will be quite etlicient in operation.

Further objects and advantages will be made evident hereinafter.

In the drawing which is for illustrative purposes only, Fig. 1 is a section through a tire to which my invention has been applied.

Fig. 2 is a side elevation thereof.

In the form of the invention shown. a bumpingblock 11 is provided with a pointed projection 12 which is of such size and shape that it will leave a distinctive mark or trail upon the surface of the street in. case the automobile is operated with the" shackle in place upon one of the wheels.

Divided and this application filed March 2,

1 6 is secured at 17 in the block 11 passing" up on the tire and being readily locked to theft end of the arm 13by a padlock-20'.

prevent unauthorlzed movement of the aur tomobile as when the automobile is moved, the bumping member 11 produces an unmis takable noise and movement and the projectionl2rleaves a plain mark ortrail-by-which the automobile may be followed;
